BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to tray devices and more particularly relates to managing tray device.

2. Description of the Related Art

A data processing system may employ one or more device trays, referred to herein as trays. The trays may mount tray devices such as hard disk drives, processors, and the like. A tray may allow a tray device to communicate with the data processing system through a connector. The tray may also provide power, cooling, and the like for the tray device.

The tray may allow an administrator to easily add tray devices to or remove tray devices from the data processing system. For example, the administrator may remove a first hard disk drive from the tray and replace the first hard disk drive with a second hard disk drive.

Data processing systems are often heterogeneous environments, with hardware components and software from many suppliers working together. As a result, standards have been developed to coordinate interoperability between hardware and software components from different suppliers.

For example, the Storage Networking Industry Association's Storage Management Initiative (SMI) was created to develop and standardize interoperable storage management technologies for the storage, networking and end user communities. The Storage Networking Industry Association published a SMI specification (SMI-S) that includes a Common Information Model (CIM). The CIM defines software classes that can be used to create objects that facilitate communications between disparate hardware and software components.

Unfortunately, SMI-S CIM does not include classes for objects that manage trays. As a result, vendors often must employ ad hoc solutions to manage trays in data processing systems.

DETAILED DESCRIPTION OF THE INVENTION

Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays (FPGAs), programmable array logic, programmable logic devices or the like.

Modules may also be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions, which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.

Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within the modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including different storage devices.

Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

Furthermore, the described features, structures, or characteristics of the invention may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

FIG. 1 is a schematic block diagram illustrating one embodiment of a tray 100 in accordance with the present invention. The tray 100 includes an enclosure 105 and plurality of tray connectors 110(a-c). Although, for simplicity only one (1) enclosure 105 and three (3) tray connectors 110 are shown, any number of enclosures 105 and tray connectors 110 may be used in the tray 100.

The tray 100 may mount tray devices. In addition, the tray 100 may allow an administrator to easily add the tray devices to and/or remove the tray devices from a data processing system. For example, the administrator may remove a first processor from the tray 100 and replace the first processor with a second processor. The tray 100 may also allow the tray device to communicate with a data processing system through the tray connectors 110. Each tray connector 110 may embody a slot for mounting tray devices.

The tray connectors 110 may mount tray devices. For example, the first tray connector 110 a may include forty-four (44) pins for mounting a hard disk drive tray device, the second tray connector 110 b may mount a processor, and the third slot 110 c may mount another hard disc drive.

The PCI module 360 may also be an expansion card as is well known to those skilled in the art.

The BIOS module 340 may communicate instructions through the south bridge module 325 to boot the computer 300, so that software instructions stored on the storage module 365 can load, execute, and assume control of the computer 300. Alternatively, the BIOS module 340 may comprise a coded program embedded on a chipset that recognises and controls various devices that make up the computer 300.

The network module 345 may communicate with the south bridge module 325 to allow the computer 300 to communicate with other devices over a network. The devices may include routers, bridges, computers, printers, and the like.
